ProSpray 3.21 9GB Starting operation64.2 Control Panel IndicatorsThe following is a description of the control panel indicators.PressureIndicatorServiceIndicatorPressure IndicatorThe pressure indicator shows the current operating pressure of thesprayer. It has three different indications: blinking yellow, solidyellow, and solid green.Blinking yellowWhen the pressure indicator is blinking yellow, the sprayer isoperating between 0 and 1.4 MPa (14 bar). A blinking yellowpressure indicator means:• The sprayer is plugged in and turned “ON”• The sprayer is at priming pressure (little or no pressure)• It is safe to move the relief valve between positions• It is safe to change or replace the spray tipi If the pressure indicator begins blinking yellow whenthe pressure control knob is set at a higher pressureand the relief valve is in the SPRAy position, eitherthe spray tip is worn or the sprayer is in need ofservice/repair.Solid yellowWhen the pressure indicator is solid yellow, the sprayer is operatingbetween 1.4 MPa (14 bar) and 12 MPa (120 bar). A solid yellowpressure indicator means:• The sprayer is at the proper pressure setting for spraying stain,lacquer, varnish, and multi-colorsSolid GreenWhen the pressure indicator is solid green, the sprayer is operatingbetween 12 MPa (120 bar) and 23 MPa (230 bar). A solid greenpressure indicator means:• The sprayer is at the proper pressure setting for spraying oil-based and latex house paints• The sprayer is operating at peak performance at a highpressure setting• If the pressure indicator goes to solid yellow when thepressure is set so that it starts at solid green, it indicates one ofthe following:a. Tip Wear Indicator — when spraying with latex or at highpressure the solid yellow appears. This means the tip isworn and needs to be replaced.b. Tip Too Large — when a tip that is too large for the sprayeris put in the gun, the pressure indicator will turn from solidgreen to solid yellow.c. Fluid Section Wear — if a solid yellow pressure indicatorappears when using a new tip and the pressure is set atmaximum, service may be required (worn packings, wornpiston, stuck valve, etc...).Service IndicatorThe Service indicator is on when the motor is commanded to run.This indicator is used by service centers to troubleshoot motorproblems.4.3 Pressure control knob settings (Fig. 5)1.
